Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] SSBR rubber of the present invention is processed by SSBR2305 base rubber, SSBR312 sizing material, new carbon black, auxiliary agent and vulcanization system, and concrete steps are as follows:

[0016] 1) Blending of SSBR2305 base rubber and SSBR312 rubber;

[0017] At a temperature of 140-155°C, mechanically stir and blend SSBR2305 base rubber and SSBR312 rubber in a ratio of 3-3.4:1, and add auxiliary agents. The dosage of nano-ZnO is 120-210phr, and stir evenly for 35 minutes , to produce a blended "rubber";

[0018] 2) At a temperature of 150°C, put 50 phr of new carbon black into the blended compound and stir evenly;

[0019] 3) Put the blended rubber into the vulcanization system and vulcanize for 50 minutes. The temperatu...

Abstract

The invention belongs to the field of machine manufacturing, and particularly relates to a preparation method for high-performance and low-thermogenesis SSBR rubber. The SSBR rubber is processed by SSBR 2305 base rubber, SSBR 312 rubber material, new carbon black, auxiliary agents and a vulcanization system, wherein the auxiliary agents comprise an anti-aging agent, an accelerant, nano-Zno, A151, and Mg(OH)2; the SSBR 2305 base rubber and the SSBR 312 rubber material are mixed. The preparation method comprises the following steps: adding the auxiliary agents into the mixed rubber materials of the SSBR 2305 base rubber and the SSBR 312 rubber material and stirring for 35 min; adding 50 phr of the new carbon black into the mixed rubber materials of the SSBR 2305 base rubber, the SSBR 312 rubber material and the auxiliary agents, and uniformly stirring; adding the mixed rubber materials of the SSBR 2305 base rubber, the SSBR 312 rubber material, the auxiliary agents and the new carbon black into the sulfur-free vulcanization system to be subjected to vulcanization for 50 minutes, wherein the temperature of the vulcanization system is 150 DEG C. According to the invention, the production efficiency is high, the product percent of pass is high, the physical and mechanical properties are excellent, the low-thermogenesis performance is excellent, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a preparation method of SSBR rubber with high performance and low heat generation. Background technique [0002] SSBR rubber is an elastomer synthesized by anionic solution polymerization of styrene and butadiene under the trigger of organic lithium. In addition to maintaining the original characteristics of rubber, it also has more excellent properties than natural rubber, such as wear resistance, heat resistance, aging resistance and vulcanization speed compared with natural rubber, and can be used with natural rubber and various synthetic rubbers. Widely used in the production of tires, tapes, hoses, wires and cables, medical appliances and various rubber products. At present, SSBR rubber is in demand in various fields and has a good application prospect. Its applicable working conditions (medium, temperature, pressure) depend on the scope of work. However...
